Abstract

The present application relates to the technical field of air conditioner defrosting, and discloses a control method for air conditioner defrosting. The control method includes: when the air conditioner enters the bypass defrosting mode, obtaining the defrosting working parameter and the defrosting attenuation parameter; if the defrosting working parameter and the defrosting attenuation parameter meet the defrosting protection condition, reducing the defrosting bypass Refrigerant flow in branch circuit. The control method provided by the embodiments of the present disclosure can control and reduce the refrigerant flow rate of the defrosting bypass branch according to the defrosting attenuation parameter and the defrosting working parameter when the air conditioner enters the bypass defrosting mode, so as to reduce the refrigerant flow rate of the defrosting bypass branch. The flow of high-temperature refrigerant used for defrosting is shunted through the bypass, thereby reducing the adverse effects of the temperature and flow of the gaseous return air refrigerant of the compressor caused by excessive refrigerant being used for defrosting, thereby reducing the adverse effects caused by the operation The defrosting ability of the air conditioner decreases over time caused by the bypass defrosting mode. The application also discloses a control device for defrosting the air conditioner and the air conditioner.

Description

technical field [0001] The present application relates to the technical field of air conditioner defrosting, for example, to a control method for air conditioner defrosting, a control device and an air conditioner. Background technique [0002] With the development of science and technology, air conditioners, as a necessary electrical equipment in the daily life of ordinary people, have gradually developed from the initial single-cooling models to advanced models with more functions such as cooling, heating and defrosting. Here For air-conditioning products that operate in low-temperature areas or in windy and snowy conditions, an important problem that inevitably needs to be faced is the frosting problem of the outdoor unit of the air conditioner. The role of the evaporator that absorbs heat in the environment is affected by the temperature and humidity of the outdoor environment in winter. More frost is likely to condense on the outdoor heat exchanger, and when the frost a...
